The corrosion rate of 2205 duplex stainless steel was 0.0255 mm/y after 720 h of high-temperature and high-pressure production environment. It can be concluded that the corrosion rate of 2205 duplex stainless steel in production environment is much lower than that in high temperature acidification environment.
About UNS S32205. UNS S32205 is a duplex grade with a ferritic-austenitic microstructure. The alloy consists of around 40-50% ferrite in the annealed condition. The duplex microstructure has the high strength of the ferritic grades whilst retaining the corrosion resistance of the austenitic grades.

Duplex stainless steels are magnetic and are far more corrosion resistant than more commonly used stainless grades, i.e. 302 and 316. Duplex is characterised by its high yield strength, as well as good fatigue strength and excellent corrosion resistance. Duplex is also known as Duplex 2205 and Cronifer 2205 LCN.
